Abstract
A method and means for efficiently utilizing bus bandwidth among processors and input/output devices burst coupled in master/slave pairs over a clocked, arbitrated, bidirectional, multistate, local communications bus. The method resynchronizes arbitrated masters and selected slaves perturbed during their bus-coupled transactions by recirculating data during a write operation at a bus master in the absence of a slave acceptance signal, or recirculating by a slave in the absence of a master response. The recirculating master or slave responsive to a delayed indication from its passive opposite then sends out the data over the bus at an integral multiple of the clock rate.
